Devices and methods for producing denture parts

Abstract

Surface mapping and / or generation device is provided, with a device for mapping 3D data of at least one denture base object such as a tooth stump or an implantation abutment, and an environment thereof, as well as with a device for the data-based generation and production of a denture part incorporating the 3D data of the denture base object. Additionally provided are a device for determining and / or defining a placement direction of the denture part that is to be slipped onto the denture base object, and a device for determining and producing a primary part that is to be slipped onto the denture base object before the denture part and that yields a desired placement direction for the denture part which is different from the placement direction that exists for slipping the primary part onto the denture base object. The device for data-based generation and production of a denture part is designed to generate and produce the latter by incorporating the 3D data of the primary part. Surface mapping and / or generation method is provided, wherein 3D data from a denture base object such as a tooth stump or an implantation abutment and an environment thereof are mapped and then, based on this 3D data of the denture base object, a denture part to be slipped thereon is produced. Before production of the denture part, a placement direction of the denture part onto the denture base object is determined or defined. On the basis of this 3D data of the denture base object, a primary part is determined and produced, with which a desired placement direction that differs from the placement direction that exists for slipping the primary part onto the denture base object is created for the denture part. On the basis of the 3D data, the denture part is generated and produced based on data so as to fit when pushed onto the primary part.

AI Technical Summary

Benefits of technology

The present invention is about improving devices and methods for producing denture parts. Specifically, the invention focuses on the development of devices and methods for partially or fully automatic edge detection of inlay preparations and for producing complex denture designs. The invention aims to optimize the production process and time by using advanced technology. The invention also includes devices for mapping and generating 3D data of denture base objects and producing denture parts based on this data. The invention can be used in combination with existing technology or on its own. The technical effects of the invention include improved efficiency and accuracy in denture production.

Problems solved by technology

In many fields of dentistry, it was previously necessary to preserve plaster casts of patients for up to 10 years, which resulted in an enormous demand for space.
